Grounding Connector System
The Technically Superior
Alternative Has Arrived
When it comes to connecting Ground, Cable
and Bus runs in the harshest conditions possible,
electrical utilities around the world trust the
rugged strength and patented technology of the
DMC Power Swage system.
The robust design and performance of our
Swage Tool and Grounding connectors meet
and exceed the rigourous testing requirements
of IEEE 837, providing your substation with
a lifetime of worry free connections and a
permanent low-resistance path to ground.
Hand held Ground Tooling is compact,
portable and easy to use in all conditions.
Discover the Advantages of
DMC Power’s Ground Connectors
■ Ultimate Performance
Made with C11000 copper and the ability to carry
the equivalent current (or greater) of the conductor,
DMC Power connectors have one of the highest
conductivity ratings at 101% IACS with a melting
point of 1981° F, ensuring your substation has the
highest level of performance and reliability possible.
■ Versatile
All weather operation reduces setup time and
costly delays.
The same tool used for Grounding Connectors can
also be used with our Cable Connectors.
■ Safe
Cold compression Swaging requires no special
protective gear and eliminates heat, open flames
and toxic fumes.
■ Reliable
Produce consistent, repeatable results with our
simple one-button operation.
360° compaction reduces voids,
allowing the fitting to run cooler.
Can’t find what you need?
Our connectors are available in a variety
of sizes to fit most jobs but when a custom
solution is needed now, turn to DMC
Power. Our in-house team can design,
test and manufacture connectors to fit any
specification or use, all under one roof at
our ISO 9001:2008 certified facilities.
■ Convenient
No molds, extra equipment, mixing shot material or
regular maintenance is required.
■ Instantly Inspectable
Confirming Swage results couldn’t be easier; our
“Go/No-Go” Inspection Gauge measures the Swage
instantly, leaving you more time to get the job done.
